the speaker size is 5x7 all around.
The 1991 Honda civic uses 6.5" speakers for both front and rear.
The speakers in the doors of a 1991 Ford Ranger are 6-inch speakers.
IN THE FRONT DOORS 5x7'S BACK 6x9'S
6 x 8 Rear 5 1/4 front in the doors
If it has the same speakers as my '98 they should be 6.5 inch in the doors and 4 by 6 on the dash.
They are 4x6.
Rear Deck Speakers Are 6x9" and the front door panel speakers are 5 1/4"
i know the measurement is six and half but that's all i got.
